Be it known that I, HENRY JWVARD, a citizen of the United States, andresident of Indiana Harbor, countyyof Lake, and State of Indiana, haveinvented certain new and useful Improvements inCarSe'als, of which thefollowing istya specificatiom-and which are illustrated in theaccompanying drawings, forming a part thereof. I v The invention relatesto car seals an more particularlyto those of-the type known as automaticseals. and, comprising a chamberedhead ajnd a'shacklefand provision forsecuring an end ofthe shackle "within the chamber of the head in such amanner that it cannot be withdrawn without destroying the seal, I

The object of the invention is to provide.

improved means for preventing the insertion of a cutting tool into thechamber of the head along the path-of the shackle and thus opening theseal by severing'the locking instrumentalities; I i I To this end theinvention use of abutting transverse shoulders formed upon a wall of thehead, and upon the shackle and in order that these shoulders maybeefiective in'preventing the insertion of a cutting tool,,,the inventionfurther contemplates a form 'of locking means constructed to hold theend of theshackle in fixed position within the chamber of {the head.

In the accompanying drawings,'Figure 1 is a central longitudinalsectional view of a seal embodying the features of improvement providedby, the invention, the parts being shown, in closed position; Fig. I2iisadetail plan View showing a blank of sheetmetal from which the partsofthe seal may be tional view taken on the line ei-toffiFig. 1, Fig. 5, isa detail perspective viewshowing the end of the'shackle, and Fig. 6 isaidetail perspective view showing a modified form of an endaof theshackle. I g The seal is conveniently formed from a single piece ofsheet metal, as 10; This sheet metal blank may be transversely foldedupon thelines 00-40 andy-y to" provide a chambered'head,1 1,a tongue 12within the chamber of the head and a str'apor shackle 13. When. formedin this way the end 14 of the chambered head 11, is left open forcontemplates the the insertion of'the free end 'ofthe strap, 13, whenthe seal is .to be closed.

which receives the depressed portion 17,0f

For engagement with this shoulder, a part ofthe strap, 13,adjacent its free end is depressed in the form of a channeledl ortion18, of the tongue 12, provides tending partway across the strap andabutting against'the transverse shoulder l9 when the end ofthe strap isthru'sti-nto the'cham ber of the head. The side portions 22, 23

of the strap :fit against the under side ofthe tongue 12, at each sideofits channel 18.

:Any convenient means may be employed for locking theend of thestrap'within the chamber of the head. Preferablyithis will take the formofa shoulder, 24, struck up wardly from the floor of the channel, 20,

of the strap, in position for engagement with the end of the tongue, 12.To insure" I the shoulders 19 and=21 being held in contact when the sealis closed, the shoulder 245'is so positioned as to justpass the endofthe tongue 12, Whenthe shoulder 21,-"comesinto engagement with theshoulder 19. The free tongue and by" sufliciently curving, the

tongue to'cause its end to elastically enter of the "strap. Thecontacting shoulders 19 and 21 serve to effectually prevent theinsertion-of a tool over the strap 13, for rais this pocket until-theinsertion of the end I nel 20, the inner end, 21,' of the channel bee-7mg in the form ofia transverse ShOulder'eX- I neled portion of thestrap, insuresthat the engagement of the tongue with the shoulder cannotbe disturbed by the insertion of a tool either below or about the sidesof the strap. The engagement of the tongue, 12, with the shoulder 24,when the shoulders 19and 21 are in contact firmly holds the end of thestrap against longitudinal length as to engage the shoulder, 24, when pthe .shoulders, 19 and 21, are exactly in con-. tact, it will beunderstood that when the seal is to be formed by automatic machinery theparts will be so proportioned aspto permit the shoulder 24 to passashort distance be yond the end of the tongue, 12., This is for thepurpose of preventing slight differ.

ences in the proportions of the parts which may occur frominterferingwith the opera-' tion of the seal.

In order that cutting through the tongue at'the shoulder, 1-9, by theinsertion of-a cutting tool above the strap 13, may not serve to openthe seal, the margins of the tongue, 12, are preferably.interfolded withthe margins of the base and cover plates, 15., 16 of the head. As shown,the tongue,

-12, is provided with lateralprojections, 26, v '27,' and the marginsofthe coverplate 16,

of the head are provided with notches 28 and 29. hen the parts arefolded together upon the line w:r, the projections 26 and 27 enter thenotches 28 and 29, respectively, and are interfolded with the margins ofthe floor plate 15-. As the base of the tongue, 12, must be separatedfrom the floor plate 15 of the head a suflicient distance .to permit theshoulder 24 .to pass between these parts, a rib, 80,is preferably struckup from the floor of the channeled portion 20 of the tongue to fill thespace between these'parts when the'seal is closed. If desired, thisspace may be filled by raising the floor of the channel 20 throughout aportion of the length of the channel for its entire width, as indicatedat 33 in Fig. 6.
